Synthesis of Secondary and Tertiary Aminofurazans. — The reaction of nitrofuralike (I) and (XIII) with primary and secondary amines proceeds with substitution
02- 120 zans
of the nitro group to furnish the secondary and tertiary title aminofurazans. A wide
range of side reactions is observed, and the reaction conditions must be optimized for
each substrate. A further expansion of the spectrum furazans is presented by reactions
using the amidoxime fragment as in (XVI). — (SHEREMETEV*, A. B.;
